How to describe the delicacy that lies within these tins? Our mackerel fillets (filetes de caballa) are simply preserved in just olive oil and salt, hand-prepared and packed and glorious. The succulent fillets are suitable for any number of tapas, but even solo make a standout snack. Have our other seafood items delighted you and your customers? Of course they have. The same such experience awaits with each of these tins.
